Specification of Letters Patent.

Application filed May 18, 1920. Serial No. 382,301.

To all whom it may concern:

Be it known that I, FERNAND DEVIENNE, a citizen of the French Republic, and residing at Paris, France, have invented certain new and useful Improvements in Apparatus for the Rapid Application of Cupping-Glasses, Suction-Cups, &c., of which the following is a specification.

The present invention has for its subject an apparatus by means or" which it is possible to apply rapidly cupping-glasses, suction cups or the like without the necessity of having recourse to processes, wherein use is made of inflammation papers or plasters, or cotton-wool impregnated with alcohol, which render the application of cuppingglasses, a delicate operation.

The apparatus is essentially characterized by the fact that the effect of the cuppingglass is obtained by producing a reduction in pressure simultaneously in the glass and in a vessel which surrounds it, in which vessel the pressure is restored, the reduced pressure existing only in the glass itself which at this moment is pressed against the skin of the patient.

In the accompanying drawing is shown diagrammatically a section of an apparatus constructed according to the present invention.

As will be seen from this figure the glass or cup 1 is inclosed in a cylindrical casing 2 forming an extension of the pump chamber 3, in which works a piston 4. Openings 5 are provided near the upper end of the pump chamber slightly in front of the end of the outward stroke of the piston 4. Guides 6, constructed tor-example of metal wires, guide the glass 1 and retain it in a suitable position. A light spring 7, resting for example against a grid 8 mounted in the lower end of the pump chamber 3, exerts a light pressure upon the glass 1, this pressure however being always insufilcient tor preventing communication of the air between the interior of the glass 1 and the interior of the casing 2.

The operation of the apparatus will be understood easily. The piston l being at the end of its inward stroke, the glass 1 being surrounded by the casing 2 and the whole apparatus being strongly pressed on the skin of the patient, then when withdrawing the piston l while holding the casing 2, integral with the pump chamber, in

position by hand, a reduction in pressure is produced inside the casing 2 which at the same time produces a corresponding reduction in pressure inside the glass 1. As soon as the piston 4 passes the openings 5, the atmospheric air rapidly enters the pump chamber and its pressure presses the glass 1 strongly against the skin of the patient; at this moment it is possible to remove the apparatus for applying another cupping glass, the effect of the suction produced under the glass'by raising the piston 4 being maintained as long as desired.

It will be understood that the apparatus hereinbefore described may be constructed of any suitable materials and may be of any convenient size. Moreover the glass 1 may be replaced by a vessel of any suitable shape and material.

In all cases the value of the reduction of pressure for the cupping-glass may be regulated as desired either by limiting the length of the stroke of the piston 4 by means of a slider or cursor placed on the pump chamber or in any other suitable position, or by regulating the stroke according to graduations on a scale provided on the piston rod.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. Apparz'itus for the application of cupping glasses comprising a casing adapted to inclose the cupping glass, means connectto the casing for producing a degree of vacuum therein, and means for removably supporting the cupping glass in the casing to permit of withdrawal of the latter from the cutting glass after the latter has been applied to the desired part.

2. Apparatus for the application of cupping glasses comprising a casing adapted to surround the cupping glass, means for supporting the cupping glass to be freely movable longitudinally of the casing, means carried by the casing for pressing the cupping glass against the desired part, and means connected to the casing for producing a degree of vacuum therein.

3. Apparatus for the application of cupping glasses comprising a casing adapted to surround the cupping glass,a pump chamber, a piston therein, said pump chamber being mounted. on the casing and communicating at one end therewith and having an opening therein near the rear end thereof, and means for resiliently pressing the cupping glass ing at one end with the casing and near its against the part to Which it is being apother end having openings therein, a piston 10 plied.
